I genuinely want someone to build nice tech to solve this problem, I have a cctv at my home and once a month a cop shows up to get some info on a crime that has happened in my area, tech like homomorphic encryption should get really really good so that searching for a image or video in a footage should not create privacy nightmare.
There is one more part that can also be done, mobile operator's can also request your wifi information like rrsi and bssid using LPP WLAN positioning, using this as well the location context can be gathered, it will be nice if apple can crib this as well.
